See where your power comes from, where it goes, and what is driving your bill.
1app.energy brings supported solar, battery, EV charging, heat pump, hot water and tariff data into one view of your whole home, with battery controls you can turn on once your setup is supported and verified.
1app connects to the hardware you already own - no new boxes, no rewiring. Onboarding focuses on the inverter, charger and tariff combinations where whole-home context is most valuable.

Connect with the SigEnergy account you use in the mySigen app. Smart Control, charge, discharge, export and hold remain off during this rollout.
Electric Vehicles & Chargers
Connect a supported Hypervolt charger for monitoring and charging history. Boost, Eco, Super Eco and Stop are beta controls once you turn on EV Smart Control. Charging targets remain managed in Hypervolt. Availability depends on Hypervolt cloud access.
Connect a compatible Pod Point charger for charger state, selected charge history and whole-home EV context. Boost, Smart or Stop mode control is available only where customer-enabled and backend-supported. Ready-by targets and full scheduling remain in Pod Home.
Heat Pumps
Monitoring
Connect a compatible Mitsubishi heat pump through MELCloud or MELCloud Home for monitoring. Setup, schedules and direct control stay in the Mitsubishi-native app.
Features and availability vary by device and provider connection.
Smart EV charging can quietly drain the battery you meant to keep.
On some supported setups, daytime EV charging can draw from stored battery energy. Your charger, inverter, tariff and heat-pump apps can each show only part of the picture, making it harder to understand the whole home or coordinate a response.
⚡
Daytime charging can use stored energy
On some supported setups, a daytime EV session can draw from the home battery before you expect it.
Energy used at the wrong time
📱
Four apps, no whole-home view
Your charger, inverter and tariff screens each show one piece of the picture. It is difficult to see the complete flow in one place.
More switching, less context
☀️
Manual schedules are easy to miss
Battery modes, EV schedules and tariff windows can fall out of sync, leaving you to check and adjust them yourself.
More admin, more room for error
📉
Heating efficiency can be hard to see
When heat-pump data sits in another manufacturer app, changes in performance and energy use can be harder to spot alongside the rest of your home.
Higher heating use can go unnoticed
Why people start looking for a fix
Poor coordination can waste energy and increase cost. The impact depends on your tariff, battery and actual usage.
How 1app.energy helps
Protect your battery. See the whole home clearly.
1app.energy brings supported solar, battery, EV, hot-water, Daikin and Mitsubishi heat-pump data, and tariff context into one view. Daikin heat pumps (through our official Daikin partnership) and compatible Mitsubishi heat pumps are added alongside a supported inverter; Mitsubishi connects through MELCloud or MELCloud Home for monitoring only. Where supported, verified and customer-enabled, battery controls can protect stored energy and respond to tariff windows.
We detect
Supported smart charging starts
1app.energy recognises a qualifying session and checks whether battery protection is available for your setup.
We protect
Battery protection responds where enabled
For eligible homes, 1app.energy can apply the configured protection response during the session.
We optimise
Use cheaper periods where supported
Where tariff data and battery controls are available, 1app.energy can schedule eligible battery charging in lower-cost periods.

Energy Events and Axle reporting
Keep energy events clear in 1app.energy.
Confirm supplier zero-price windows, and bring in Axle events from your Axle connection or a quick prompt, each with the right owner. 1app.energy keeps supported automation, tariff accounting and Axle event value clear, while each provider remains responsible for its own terms and official payment.

Controls in one place
Everything is controlled flawlessly with full live visibility.
I use 1app.energy with Fogstar batteries, a Solis hybrid inverter, Zappi Glo and Octopus Go. The value is having battery charging, home coverage and tariff timing working from one clearer place instead of trying to line up separate apps every evening. It makes the whole setup feel easier to trust.
The Solis app gave me data, but not peace of mind.
I still found myself checking different screens, guessing what the battery was doing, and trying to work out the day manually. 1app.energy pulls the solar, battery, grid, home usage and tariff picture together. For a home with this much hardware, it feels like the missing software layer I expected after installation.

See if EV uses battery
The stressful part was never plugging in the car.
It was wondering whether the EV was quietly pulling from the battery, whether it matched the cheap-rate window, and what it meant for the rest of the house. 1app.energy makes the EV, battery and tariff behaviour easier to understand, and where supported, helps protect stored energy from the wrong kind of charging.
EV and smart tariff household
One live home dashboard
Well designed, takes a lot of the effort out of running a modern home.
A clear, reliable app for managing a three-phase home energy setup in one place. The value is seeing usage, battery and EV charging together on one dashboard instead of checking separate apps for each part of the system. It makes daily decisions feel less manual.
Axle Energy events were exactly the kind of thing I would have tracked in a spreadsheet.
Then I would have forgotten about it, or mixed it into normal export numbers. Having Axle credit shown separately from normal export credit makes the report clearer and saves me from doing my own manual maths after every event. It keeps the reward visible beside the normal export story.

See why cost changed
Before 1app.energy, I could see numbers, but not always the story.
Now I can see what came from solar, what came from the battery, what came from the grid, and how the home actually used energy. That breakdown makes the whole setup feel more trustworthy because I can understand why the day cost what it did, and what changed underneath the total.

Match battery to tariff
The battery used to feel like something I owned but did not fully control.
I knew it was charging and discharging, but not always whether it matched the tariff or the house. 1app.energy helps connect the battery behaviour with off-peak periods, EV demand and home usage, so I feel more confident leaving the system to do its job without checking it constantly.

Stop switching apps
Once you have solar, batteries, an EV charger and a time-of-use tariff, separate apps become tiring.
Each one shows a slice, but none of them explain the home. 1app.energy gives the joined-up view I expected from the start. For me, it is a no-brainer because it makes expensive equipment easier to understand and use day to day.
